Solution steps

(7) (4.5 \cdot 1 0^{- 9})

Apply rule:

(a) = a

(7) = 7

= 7 \cdot 4.5 \cdot 1 0^{- 9}

Multiply the numbers:

7 \cdot 4.5 = 31.5

= 31.5 \cdot 1 0^{- 9}

= 1 0^{- 9} \cdot 31.5

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

1 0^{- 9} = \frac{1}{1 0 ^{9}}

= \frac{1}{1 0 ^{9}} \cdot 31.5

1 0^{9} = 1000000000

= \frac{1}{1000000000} \cdot 31.5

\frac{1}{1000000000} \cdot 31.5 = \frac{31.5}{1000000000}

= \frac{31.5}{1000000000}

Divide the numbers:

\frac{31.5}{1000000000} = 0.0000000315

= 0.0000000315
